有没有办法在for循环python中分配对象

Question

我有一个名为 MediaFiles 的类，我从用户那里获取了一个路径，我从中获取了完整路径、文件名和文件扩展名，我想要做的是存储这些中的每一个

Answer 1

It sounds like you should use a list of MediaFile objects. First you need to create the list:

media_files = []

Then you append elements to the list in your for loop:

media_files.append(MediaFile(name, filepath, extention))

Answer 2

You can create a list and then store your objects there:

Below is the code:

#Define class in file named MediaFile.py
class MediaFile:

def __init__(self, file_name, file_path, file_type, file_comment=None, categorys=None, playlists=None):
        self.file_name = file_name
        self.file_path = file_path
        self.file_type = file_type
        self.file_comment = file_comment
        self.categorys = categorys
        self.playlists = playlists

    # New file which contains actual code:
    from MediaFile import MediaFile
    import os.path

    filenames = []
    filepaths = []
    fileextentions = []
    # empty list to store objects
    media_list=[]

    d = input('Enter a path to organise: ')
    for path in os.listdir(d):
        full_path = os.path.join(d, path)
        i=0
        if os.path.isfile(full_path):
            filepath = full_path
            name = os.path.splitext(os.path.basename(full_path))[0]
            extention = os.path.splitext(full_path)[1]
            i+=1
            # append the objects to a list
            media_list.append(MediaFile(name, filepath, extention))
